STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable to this application.

BACKGROUND Field

Example embodiments in general relate to a catch drawer litter box for the recovery of litter and prevention of unwanted dispersal outside of a litter box.

Related Art

Any discussion of the related art throughout the specification should in no way be considered as an admission that such related art is widely known or forms part of common general knowledge in the field.

A litter box, which is sometimes referred to as a sandbox, is an indoor waste collection box for small animals. They are typically used inside homes and dwellings where the occupants have house cats as pets. As its name suggests, a litter box contains litter, which in this context, refers to a type of gravel that is well-suited to handle urine and animal feces. When used for house cats, the litter is generally referred to as cat litter. Ideally, a house cat will preferentially use a litter box for elimination of bodily waste. After elimination, the house cat will usually use its paws to kick or cover its waste products with litter.

Because this waste removal process includes a cat using its paws to cover its waste products, it may result in litter being propelled in arbitrary directions. Depending on the configuration of the litter box, this may result in litter being propelled outside of the litter box into the surrounding area. In addition, litter may adhere to the cat's paws during this process. Once the cat leaves the litter box, this litter will tend to be spread across areas along the cat's immediate path. Thus, such litter could be found some distance away from the litter box. Because used litter is likely to contain urine and feces, its spread may present a health and cleanliness problem.

In order to control the spread of litter throughout a home containing a house cat, various solutions have been used. In some cases, a litter box is placed within a covered enclosure with a single opening for entry and exit of a house cat. This type of litter box prevents the spread of litter in directions other than that of the entry opening. Although the spread of litter during the burial portion of the process is reduced, it may still occur in the direction of the entrance, which is adjacent to the litter. Moreover, this does nothing to prevent the spread of litter that may be attached to the cat's paws.

In other cases, adhesive pads may be placed near the entrance of the litter box. If the cat chooses to walk across the pad, some of the litter stuck to the cat's paws may be stuck to the adhesive pad. However, as it is used, the adhesive pad becomes less effective. Therefore, it must be monitored and replaced to maintain its effectiveness. Moreover, any litter that becomes stuck to the pad cannot be used. Thus, the litter in the litter box must be replaced more frequently. Moreover, some cats will avoid sticky surfaces, which means that the cat will avoid the adhesive pad making it ineffective, or worse, avoid the litter box entirely and find a new place for waste elimination that is less desirable for the owner.

What is needed is a litter box solution that prevents the spread of litter and recovers any litter that might otherwise spread throughout home. Such a litter box solution may include seamless walls so urine can't leak out of the sides and onto the floor. A grate may be provided which is large enough that the cat has to take multiple steps to remove the litter from its paws. The entry to the box and litter area may be configured in an adjacent manner that forces the cat to have to walk across the grate. The entry and interior walls may also be designed in a way to keep dogs out, as dogs will often be attracted to the contents of litter boxes. A drawer under the grate may be used to catch excess litter to be recycled back into the box or disposed of. Windows may be provided for viewing and venting so the cat can see and doesn't feel trapped in the box. A charcoal filter may be positioned within a vent if desired. Holes in the side of the walls may be provided so that the scoop can be hung inside the box to reduce mess outside the box. The entry and interior walls may be designed in a way that helps contain litter within the box when the cat aggressively digs in the litter and flings it everywhere. The entry to the box may be designed with one small step into the box so that most any cat, regardless of age or disability, can easily enter and exit the box.

DETAILED DESCRIPTION A. Overview

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 11 illustrate a catch drawer litter box 10 including a base 20 and a cover 11. Base 20 generally comprises a recovery region 21, a litter region 23, and a base divider 26 separating these two regions. In some embodiments, base 20 may comprise a plurality of sides. The recovery side of base 20 is the side that is adjacent to recovery region 21 and is not adjacent to litter region 23. The litter side of base 20 is the side that is adjacent to litter region 23 and is not adjacent to recovery region 21. Common sides of base 20 include sides that are adjacent to both recovery region 21 and litter region 23. Litter region 23 generally comprises a litter container 24 configured for the receipt of litter 25 comprising litter particles. Recovery region 21 generally comprises a grate 22 comprising openings large enough to allow passage of particles of litter 25, and a recovery drawer 30 configured for removable deposition within recovery region 23 via an opening 27 in the recovery side of base 20. Recovery drawer 30 is configured for receipt of at least a portion of the particles of litter 25 that pass through the openings in grate 22. Litter box cover 11 is generally configured to enclose the recovery region 21 of base 20 and the litter region 23 of base 20 and comprises an opening 14 that is adjacent to the recovery region 21. Opening 14 is configured to allow passage of a cat 40 to litter 25 by passing over grate 22. In some embodiments, the top 15 of cover 11 is removably attached and includes a cover handle 12.

B. Base

As best shown in FIGS. 4 and 5, a base 20 for use with a catch drawer litter box 10 generally comprises a recovery region 21 and a litter region 23. The recovery region 21 generally includes a grate 22 that is configured above a recovery drawer 30. The litter region 23 is generally configured to house a litter container 24. The litter container 24 is configured to receive and hold a quantity of litter 25 comprised of numerous particles. A base divider 26 may be used to separate the recovery region 21 from the litter region 23. The base 20 will generally include a recovery drawer opening 27 that is configured to receive a recovery drawer 30 that can be placed beneath grate 22. Typically, grate 22 and recovery drawer 30 are configured such that litter particles smaller than the openings in grate 22 will fall directly into recovery drawer 30. However, a plurality of grates 22 or a single grate 22 comprised of multiple layers may be used.

The litter region 23 of base 20 is configured in a manner that makes litter 25 available for waste elimination by cat 40. Litter 25 is generally held within a litter container 24. In some embodiments, litter container 24 is integrated into base 20. In other embodiments, as illustrated in FIG. 3, litter container 24 can be removed from base 20 for easier cleaning or replacement. Litter container 24 may also be comprised of multiple pieces that collectively hold litter 25. In some embodiments, litter container 24 may also comprise a removable liner that rests within litter container 24. In other embodiments, litter container 24 includes a filter than can be removed to quickly remove clumps of litter that form due to waste elimination by cat 40.

Although the base 20 shown in FIGS. 1 through 10 comprises a rectangular profile, other profiles are suitable for use with a catch drawer litter box 10. For example, base 20 may include an oval shape, an elongated hexagon, or an irregular egg shape.

C. Recovery Drawer

A recovery drawer 30 for use with a catch drawer litter box 10 is generally configured to be removably disposed within base 20 and beneath grate 22. In general, recovery drawer 30 is configured to capture any particles of litter 25 that pass through grate 22. However, in some embodiments, grate 22 may partially rest upon an impervious surface such as a lip or border used to support grate 22 and define recovery region 21. In such an embodiment, particles of litter 25 may become trapped such that they do not enter recovery drawer 30. In general, recovery drawer 30 will abut base divider 26 when fully inserted into base 20.

In some embodiments of a catch drawer litter box 10, recovery drawer 30 comprises a portion of base 20, such that removable of the recovery drawer 30 removes at least a portion of the sides of base 20. In this type of embodiment, base 20 may comprise one or more posts or a frame without sides. Moreover, base divider 26 may be completely absent, or be comprised of a portion of recovery drawer 30. For example, the recovery drawer 30 may abut a litter container 24 directly rather than a base divider 26 that is a fixed feature of base 20.

Although the recovery drawer 30 shown in FIGS. 1 through 10 is configured for removable attachment via the side of base 20 that is furthest from litter container 24 (i.e., recovery side), recovery drawer 30 may also be configured for removal from one of the sides adjacent to litter container 24 (i.e., common side). For example, if the catch drawer litter box 10 is placed in a corner or adjacent to a wall, it may be advantageous for recovery drawer 30 to be configured for removable deposition into recovery region 23 via an alternate side of base 20.

D. Litter Box Cover

In order to prevent the unwanted dispersal of litter 25 to surrounding areas as part of the waste elimination process, catch drawer litter box 10 will generally include a litter box cover 11. Litter box cover 11 is generally configured to enclose recovery region 21 and litter region 23 of base 20. In some embodiments, litter box cover 11 is comprised of a plurality of litter box sides 13, a litter box opening 14, a litter box top 15, and a cover handle 12. Litter box sides 13 and litter box top 15 prevent cat litter 25 from being dispersed in the areas surrounding the catch drawer litter box 10. Litter box sides 13 and litter box top 15 also provide privacy for cat 40 and concealment of litter 25 for the owner. Litter box opening 14 permits cat 40 to enter and exit the catch drawer litter box 10. The litter box opening 14 is generally configured such that cat 40 must pass over grate 22 in order to reach cat litter 25. However, in some embodiments, litter box opening 14 may have a different shape or location along litter box sides 13. For example, litter box opening 14 may be located on a corner rather than a side. In this type of embodiment, cat 40 may have to turn to the right or left in order to reach litter 25.

Litter box cover 11 may also include a cover handle 12 to aid in the temporary removal of litter box cover 11 or a portion thereof from base 20. In the example shown in FIGS. 2 and 3, a cover handle 12 is attached to litter box top 15, which is removable from litter box sides 13. In some embodiments, one or more cover handles 12 may be attached to litter box sides 13 in addition to or in lieu of a cover handle 12 attached to litter box top 15. In some embodiments, litter box sides 13 and litter box top 15 are configured to form a single unitary structure. In other embodiments, litter box cover 11 may comprise a single structure without clearly identifiable litter box sides 13 and litter box top 15. For example, if litter box cover 11 is comprised of a single unitary structure with a dome shape, there may be no meaningful distinction between litter box sides 13 and litter box top 15. However, even with a dome shaped litter box cover 11, an upper portion of the litter box cover 11 may be independently removable and considered to be litter box top 15. Similarly, a side portion of litter box cover 11 may be independently removable and considered to be a portion of litter box sides 13. In addition, a portion of litter box cover 11 may be hinged such that a temporary opening can be created without complete removal of that portion from litter box cover 11. In addition to surrounding recovery region 21 and litter region 23 while resting upon base 20, as shown in FIGS. 1 through 9, litter box cover 11 may also be configured to surround the entire base 20.

In addition to configurations of litter box cover 11, wherein the litter box cover 11 is independent of base 20, one or more portions of litter box cover 11 may be integrated into base 20. For example, litter box sides 13 may be integrated with base 20. In this embodiment, litter box top 15 may be the only removable portion of litter box cover 11. In other embodiments, litter box top 15 and a portion of litter box sides 13 are removable from litter box cover 11 as a single structure. In some embodiments, such as the one shown in FIG. 10, the entirety of litter box cover 11 may be integrated with base 20.

E. Operation of Preferred Embodiment

In a preferred embodiment, with reference to FIG. 3, catch drawer litter box 10 is comprised of a base 20 and separate litter box cover 11, with the litter box cover 11 being comprised of litter box sides 13 and a separate litter box top 15. Base 20 comprises a recovery region 21 and a litter region 23 that are defined by four sides and a base divider 26. There is a separate litter container 24 that is configured to rest within litter region 23 of base 20, and a grate 22 that is configured to cover recovery region 21 of base 20. Base 20 also includes a recovery drawer 30 that is configured to be removably disposed within base 20 through an opening 27 so as to fit underneath grate 22.

The base 20 is placed in a preferred location for waste elimination. The grate 22 is put in place in the recovery region 21 of base 20. Litter container 24 is placed within the litter region 23 of base 20. A few inches of litter 25 is placed within litter container 24. Recovery drawer 30 is inserted into recovery drawer opening 27 of base 20, such that it rests underneath grate 22. The litter box sides 13 of litter box cover 11 are placed on base 20 so as to enclose recovery region 21 and litter region 23 with litter box opening 14 located near recovery region 21. Litter box top 15 is then placed on top of litter box sides 13 to complete the litter box cover 11 and fully enclose the space above of base 20. At this point, an exemplary catch drawer litter box 10 is in place for use by a cat 40.

As shown in FIG. 11, a door or flapper 84 may be attached to the housing to selectively close the opening 14. The door or flapper 84 may be comprised of various types of doors or flappers commonly used in the pet industry to selectively close openings.

At various times after the catch drawer litter box 10 has been configured, cat 40 will enter via litter box opening 14, as shown in FIG. 6. Cat 40 will walk across grate 22 in recovery region 21 to reach the litter 25 that is held within the litter container 24 in litter region 23. Cat 40 will then use the litter 25 for purposes of waste elimination. This is generally followed by cat 40 attempting to bury its waste within the litter 25 held in litter container 24. This process of burying waste generally involves cat 40 using its paws to kick particles of litter 25 in the direction of the waste. Stray particles of litter 25 will generally bounce off litter box sides 13 and litter box top 15 and remain within the interior of the catch drawer litter box 10. Ideally, the majority of the stray particles of litter 25 will be reflected back into litter container 24. However, some of the particles will enter the recovery region 21, pass through the openings in grate 22, and land in recovery drawer 30. Still other particles of litter 25 will stick to the paws of cat 40. Ideally, very few particles of litter 25 will leave the catch drawer litter box 10 via opening 14. Having finished burying its waste, cat 40 will walk across grate 22 to exit catch drawer litter box 10 via opening 14, as shown in FIG. 7. The process of walking across grate 22 will generally cause any particles of litter 25 that are stuck to the paws of cat 40 to fall through the openings in grate 22 and into recovery drawer 30.

After one or more instances of waste elimination by cat 40, with the aid of drawer handle 31, recovery drawer 30 can be removed from base 20 as shown in FIG. 8. Recovery drawer 30 will generally include particles of litter 25 that have been kicked by cat 40 during waste burial and particles of litter 25 that have been scraped from the paws of cat 40 while exiting the catch drawer litter box 10. This recovered litter can either be discarded or returned to litter container 24 to replenish any litter 25 that may have been removed, such as during the cleaning of litter container 24. In some cases, recovery of litter 25 may occur immediately after litter container 24 has been cleaned. To the extent that litter 25 beyond that which was recovered in the recovery drawer 30 is needed, litter 25 can be replenished using fresh litter. After any particles of litter 25 in the recovery drawer 30 have been dealt with, recovery drawer 30 is returned to base 20 via recovery opening 27, as shown in FIG. 9. catch drawer litter box 10 is now available for additional use by cat 40.

As best shown in FIGS. 15-23, the cavity 60 of the container 50 may be divided between a recovery region 70 and a litter region 78. The recovery region 70 is generally positioned at the entry point of the container 50, such as behind the entry opening 59. The recovery region 70 is utilized for the animal 40 to clear debris 46 off its paws prior to exiting the container 50 after using the litter region 78. The litter region 78 is utilized by the animal 40 during excretion of waste 45.

A cleaning tool 42 such as a scoop may be stored within the cavity 60, such as within the recovery region 70 as shown in FIG. 15. The manner in which the cleaning tool 42 may be stored within the cavity 60 may vary in different embodiments. As a non-limiting example, FIG. 15 illustrates that the cleaning tool 42 may be hung from a wall within the cavity 60. In some embodiments, the container 50 may comprise an opening where a hook may be inserted on which to hang the cleaning tool 42. In other embodiments, a shelf, looped connectors, adhesives, or other methods may be utilized for removably securing the cleaning tool 42 within the cavity 60.

As shown in FIGS. 16-23, the cavity 60 of the container 50 may include a divider 61 which is positioned between the recovery region 70 and the litter region 78 of the container 50. The divider 61 may serve as a barrier between the recovery region 70 and litter region 78. The shape, size, orientation, and positioning of the divider 61 may vary between different embodiments.

The exemplary embodiment shown in the figures illustrates the divider 61 as being offset from the centerline of the container 50 between its first and second sides 55, 56. This configuration results in a recovery region 70 which is narrower in width than the litter region 78. It should be appreciated that alternate placements of the divider 61 in different embodiments may result in different width ratios between the recovery and litter regions 70, 78. For example, the divider 61 could be positioned at the halfway point between the first and second sides 55, 56 of the container 50, resulting in recovery and litter regions 70, 78 which are of equal width. Alternatively, the divider 61 could be positioned such that the recovery region 70 is wider than the litter region 78.

The divider 61 may include a transfer opening 64 through which the animal 40 may transit between the recovery region 70 and the litter region 78. The animal 40 will generally walk through the transfer opening 64 in a first direction to go from the recovery region 70 to the litter region 78, and then return through the transfer opening 64 in a second direction to go from the litter region 78 to the recovery region 70.

FIGS. 15 and 16 illustrate an exemplary embodiment of a divider 61 in use to separate the cavity 60 of the container 50 between a recovery region 70 and a litter region 78. The illustrated embodiment utilizes a divider 61 which has a first portion 62 and a second portion 63. The first portion 62 extends at a first height from the front of the container 50 toward the rear of the container 50. The second portion 63 extends at a second height from the rear of the container 50 toward the front of the container 50 to meet halfway with the first portion 62.

In the illustrated embodiment, the second portion 63 is shorter than the first portion 62 so as to define the transfer opening 64 between the regions 70, 78. It should be appreciated that the reverse configuration could be utilized, with the first portion 62 being shorter in height than the second portion 63. In other embodiments, the divider 61 may comprise a uniform height, with the transfer opening 64 being formed within the divider 61.

As best shown in FIGS. 15 and 16, the cavity 60 of the container 50 is divided between a recovery region 70 and a litter region 78. The recovery region 70 is positioned at the entry/exit point for the cavity 60 of the container 50 directly behind the entry opening 59 on the front end 53 of the container 50. After an animal 40 such as a cat has used the litter region 78, the animal 40 will be forced to pass through the recovery region 70 which will clear its paws of debris prior to exiting the container 50.

iii. Debris Container

As shown in FIGS. 16-18, the recovery region 70 may include a debris container 75 which covers the lower end 52 of the container 50. While the figures illustrate that the debris container 75 is removably connected to the container 50, it should be appreciated that, in some embodiments, the debris container 75 may be fixedly or integrally connected to the container 50.

The debris container 75 will generally include a grate 76 at its upper surface, with a cavity defined beneath the grate 76. The grate 76 is configured such that debris 46 will be drawn off of the paws of the animal 40 and fall through the grate 76 into the debris container 75 to be retrieved and cleared later. The shape, size, and number of openings that form the grate 76 may vary in different embodiments and should not be construed as limited by the exemplary figures.

As shown in FIGS. 17 and 23, an exemplary embodiment may comprise a debris container 75 which is removably connected to the container 50. In such an embodiment, the debris container 75 may be inserted into the container 50 and removed from the container 50 through the entry opening 59.

The cavity 60 of the container 50 may include a flange 72 which acts as a guide for the debris container 75 as it is inserted into or removed from the cavity 60 of the container 50. Projections 73 such as tabs or the like may be utilized to selectively and removably engage with the debris container 75 so that it may be removably secured within the container 50. Although not shown, various other devices could be utilized to removably secure the debris container 75 within the cavity 60, such as but not limited to clasps, brackets, buckles, ties, magnets, fasteners, and the like.

iv. Cover

As shown in FIGS. 14 and 15, a cover 80 may be removably connected to the upper end 51 of the container 50 so as to selectively cover the upper opening 66 of the cavity 60. The cover 80 may comprise substantially the same shape and/or size as the upper end 51 of the container 50, or may comprise different shapes and/or sizes. The cover 80 may be connected by frictional engagement such as shown in the figures, or may be secured by other methods such as but not limited to clasps, brackets, buckles, ties, magnets, fasteners, and the like. A vent 82 may be positioned on the cover 80 such as shown in FIG. 14 to provide venting to the cavity 60 when it is covered by the cover 80. In some embodiments, the vent 82 may be configured to receive a filter, such as a charcoal filter to reduce odors permeating from the cavity 60.

v. Operation of Alternate Embodiment

FIGS. 19-22 illustrate the catch drawer litter box 10 in use. As seen in FIG. 19, an animal 40 such as a cat will first enter into the cavity 60 through the entry opening 59 of the container 50. After passing through the entry opening 59, the animal 40 will be in the recovery region 70 standing on the grate 76 as shown in FIG. 19.

As shown in FIG. 20, the animal 40 may then turn at a right angle to traverse through the transfer opening 64 into the litter region 78 which will have previously been filled with litter 44. The litter 44 may be stored directly within the litter region 78 of the container 50, or a separate litter box may be positioned within the litter region 78, with the separate litter box storing the litter 44. In either case, the animal 40 will stay within the litter region 78 to evacuate waste 45 such as feces. Animals 40 such as cats will often play with or bury the waste 45, which collects debris 46 such as clumps of litter 44 on the paws of the animals 40.

As shown in FIG. 21, after eliminating waste 45 in the litter 44 of the litter region 78, the animal 40 will pass back through the transfer opening 64 and into the recovery region 70. The animal 40 is forced to pass through the recovery region 70 to exit the container 50 so that the recovery region 70 may recovery debris 46 from the paws of the animal 40. When passing over the recovery region 70, debris 46 will fall off of the paws of the animal 40, through the grate 76, and into the debris container 75. The animal 40 may then pass through the entry opening 59 to exit the container 50 as shown in FIG. 22.

As shown in FIG. 23, the debris container 75 may be periodically removed through the entry opening 59 to be emptied. In some embodiments, the grate 76 may be removable so that the debris container 75 may be dumped out, such as in the trash or recycled back into the litter region 78. The debris container 75 may then be reinserted into the container 50 through the entry opening 59 and secured therein by the flange 72 and projection 73 such as shown in FIG. 16 awaiting further use. The litter 44 may also be periodically cleaned out of the litter region 78 and replaced with clean litter 44 as needed.
